Inhaul cable and bridge body natural vibration prevention structure
In order to solve the problem that bridge inhaul cables and bridge steel beams are affected by wind or wind and rain together, wind vibration or wind and rain induced vibration or vortex vibration and the like are prone to being generated, and the bridge inhaul cables and bridge bodies are undoubtedly damaged, the wind and rain induced vibration prevention structure of the inhaul cables and the bridge bodies is invented as follows: one biomimetic structure is used for simulating the growth direction of plant stem thorns or leaf thorns, and the other biomimetic structure is used for simulating the growth direction of plant stem thorns or leaf thorns; the method is characterized in that when the first inhaul cable outer cover (1) is installed, bolts and screws of the first outer cover (1) are installed by imitating the growth direction of plant stem thorns, or leaf thorns imitating plants are installed on a bridge body of the inhaul cable bridge, and the second structure is irregular, and when the first inhaul cable outer cover (1) is installed, the installation direction of the bolts and screws of the first outer cover (1) is irregular, and the installation direction of the bolts and screws of the second outer cover (1) is irregular. Or irregular thorns are mounted on the bridge body of the cable bridge; the three-spiral-line structure is characterized in that bolts and screws of the first outer cover (1) are installed according to the azimuth path of a spiral line, or thorns are installed on a bridge body according to the azimuth path of the spiral line.
桥拉索、桥钢梁因受风或风雨的共同影响，容易产生风振、或风雨激振或涡振等，其无疑对桥拉索及梁体带来危害，未解决上述问题，发明了拉索及桥梁体防风雨激振的结构：其一仿生物结构，依据是模仿植物茎刺或叶刺的生长方位，其特征在于安装拉索外罩一(1)时，外罩一(1)的螺栓螺丝模仿植物茎刺的生长方位安装，或在拉索桥的桥梁体上安装模仿植物的“叶刺”，其二无规律结构，其特征在于安装拉索外罩一(1)时，外罩一(1)的螺栓螺丝安装方位无规律，或在拉索桥的桥梁体上安装无规则的“刺”；其三螺旋线结构，其特征在于外罩一(1)的螺栓螺丝按照螺旋线的方位路径安装，或在桥梁体按照螺旋线的方位路径安装“刺”。
